Sure-Flex Plus 4-Way flexing action absorbs all types of shock, vibration and misalignment

Torsional Sure-Flex Plus coupling sleeves have an exceptional ability to absorb torsional shock and dampen torsional vibrations. The EPDM and Neoprene sleeves wind up approximately 21° No Lubrication, Trouble-Free Operation torsionally at their rated torque. Hytrel sleeves will wind up about 7°. The teeth of the sleeve lock into the teeth of the flanges without clamps or screws, tightening under torque to provide smooth transmission of power. Angular Couplings are not affected by abrasives, dirt or The unique design of the Sure-Flex Plus moisture, eliminating the need for lubrication or coupling’s teeth allows for the absorption of angular misalignment without wear. maintenance and providing clean, dependable, quiet Refer to page F1-18 for misalignment performance. limits. Angular alignment can be achieved using only a scale and calipers.

B. Determine Service Factor using Load Symbol and driveR. Load L M H Symbol Light Medium Heavy Standard AC Motor DC Shunt Motor 1.25 1.5 2.0 Engine, 8 or more cylinders High Torque AC Motor DC Series & Comp. 1.5 2.0 2.5 Engine, 4-6 cylinders Engine, 3 cylinders or less 2.0 2.5 3.0 Turbine 1.0 1.25 1.5

On applications involving varying torque loads, design around the maximum load. Then determine the resulting service factor at minimum load. If this value is greater than 5.2 for EPDM or Neoprene sleeves, or 4.0 for Hytrel sleeves, special coupling alignment will be required (see page F1—18). Caution: Applications involving reciprocating engines and reciprocating driven devices are subject to rotational vibrational critical speeds which may destroy the coupling.

Selection C. Determine Size using Coupling Rating Tables

1. For 860, 1160, 1750 or 3500 RPM, use table on page F1-8.

2. For other speeds, find the coupling size by calculating HP rating @100 RPM: HP @ 100 RPM = HP x Service Factor x 100 / coupling RPM In the table below, choose a coupling with a HP@100 rating greater than calculated above. Example: For 4 HP @ 55 RPM and 1.25 Service Factor: HP @ 100 = 4 x 1.25 x 100 / 55 = 9.1 Use #11 EPDM or Neoprene or #9 Hytrel

Do not exceed a 5.2 Service Factor for EPDM or Neoprene sleeves, or 4.0 for Hytrel sleeves.

FLANGES C Type J flanges sizes 3, 4 and 5 are TEC TE manufactured of sintered carbon steel. The powdered metal manufacturing process provides high dimensional accuracy and uniform material properties for high strength. Size 6 is made of high strength cast iron.

D H Flanges are bored-to-size for a slip fit on D H standard shafts. The outside face of the flange is precision machined, allowing the surface to be used to align the coupling without special tools.

Type J flanges can be used with EPDM and Neoprene sleeves. Each flange has a standard keyway, one setscrew over the keyway and one setscrew at 90° from the keyway.

L COUPLINGS GL G Spacing between internal flange hubs equals G. Spacing between shafts should be greater than 1/8 in. and less than L minus .85 times the sum of the two bore diameters.

D To order couplings, refer to the part D number examples on page F1-3. When specifying Type J flanges, the coupling and bore sizes accompany the flange symbol "J". For example, 3J x 1/2 is 3J12. TO REMOVE SLEEVE X TO REMOVE SLEEVE X

FLANGES Type B flanges are made of C1 T E high-strength cast iron and are designed to accommodate Wood’s Sure-Grip Bushings for easy installation and removal.

BUSHINGS C2 D F Sure-Grip Bushings offer convenient mounting of the flange to the shaft securely without setscrews. They are tapered and are split through both the bushing flange and taper to provide a clamp fit, eliminating wobble, vibration and fretting corrosion. This is the same bushing used in Wood’s sheaves and pulleys and is readily available everywhere.

Selection Dimensions CLAMP HUB – SPACER DESIGN FLANGES C C ® TETE Sure-Flex Plus Type C Clamp Hub flanges employ integral locking collars and screws to assure a secure shaft connection without marring the shaft surface. One setscrew is furnished over the key. The clamp hub flange H H is often used in applications that require easy seal replacement on equipment using face seals, as the clamp hub eliminates the need for a second set screw at 90 degrees from the key. COUPLINGS

L Type C Clamp Hub Couplings can use all G L sleeve types shown on page F1-5. Type C G couplings may often be used where spacer couplings are required. Spacing between internal flange hubs equals G.

Installation Instructions

Installation Instructions Sure-Flex Plus flanges (outer metallic parts) and sleeves (inner Check angular alignment with a caliper. Measure from the elastomeric elements) come in many sizes and types. First, 6 outside of one flange to the outside of the other at intervals determine the size and type of components being used. Check around the periphery of the coupling. Determine the maximum maximum RPM values in the table below against operating and minimum dimensions without rotating the coupling. The speed. Remove all components from their boxes, and loosely difference between the maximum and minimum must not exceed assemble the coupling on any convenient surface. ((If using a the figure given under “Angular” in the table. If a correction is two-piece E or N sleeve, do not install the wire ring at this time.) necessary, be sure to recheck the parallel alignment. Inspect all coupling components and remove any protective G1 (ref) 1 coatings or lubricants from bores, mating surfaces and fasteners. Remove any existing burrs, etc. from the shafts. Slide one coupling flange onto each shaft using 2 keys where required. When using Type B flanges, follow the instructions furnished with the Sure-Grip bushings. Position the flanges on the shafts to approximately achieve 3 the G1 dimension shown in the table. It is usually best to have an equal length of shaft extending into each flange. Move one flange to its final position. Torque fasteners to proper values. Slide the other flange far enough away to install the sleeve. With a two-piece sleeve, do not move the wire ring to its final position; allow it to hang loosely in the groove adjacent to the teeth.

If the coupling employs the two-piece sleeve with wire 7 ring, move the ring into its groove in the center of the sleeve. If necessary, use soapy water and lever the ring with a blunt tool. 8 Install coupling guards per OSHA requirements.

CAUTION: Coupling sleeves may be thrown from the coupling assembly with substantial force if subjected to a severe shock load.

Note: The above applications depict the generally accepted conditions encountered in industry. Conditions subject to extreme temperatures, abrasive dusts, corrosive liquids, excessively high starting torques, etc., must be considered as extra heavy shock loads. These conditions will increase service factors. Consult TB Wood’ s for these selections.

C. Calculate Design Horsepower or Design Torque • If Prime Mover is a 970, 1450, or 3000 rpm motor. Design KW = Prime Mover KW x Service Factor Go to page F2—9 and reference the corresponding motor rpm column. • If Prime Mover is not one of the three speeds listed above. Design KW @ 100 rpm = (Primer Mover KW x Service Factor x 100) / Coupling RPM Go to page F2—9 and reference KW @ 100 RPM column. • If Using Prime Mover Torque Design Torque = Prime Mover Torque x Service Factor Go to page F2—9 and reference Torque column.

Features

Principal of Operation

Positive protection against the damaging effects of shock loads, impact loads and vibration.

The grid is torsionally flexible. The circumferential flexibility is progressive due to the curved profile of the grooves – ‘state-of-the-art’ in resilient coupling design.

Accommodating Shaft Misalignment and End-Float

The grid will accommodate combinations of misalignments present at set-up or occurring during machine displacement, settlement, etc.

Limited End-Float kits are available on request.

Parallel Angular End-Float Effectiveness of Torsional Damping

As the grid coupling transmits torque, the flexing of the tapered grid spring damps Tssso so vibrations and cushions shock loads. o d o

3 This unique characteristic is due to the torsional flexibility of the coupling being proportionate to the unsupported length of each flexible grid rung. The resultant 2 16 Tssso so

reduction in peak loading protects and extends the life of the transmission Amplitude of shock 1 d o

equipment.

Versatile Design

Both 1000T10 and 1000T20 couplings feature identical hubs and grid springs, the different cover styles provide great versatility – one is horizontally split “T10”, the other is vertically split “T20”.

All coupling components are designed to be interchangeable with other taper grid couplings. The stock coupling can be used vertically or horizontally without modification.

Easy Installation and Maintenance

The grid springs are easily installed by hand or with a soft mallet. The cover fasteners can be tightened with standard wrenches. Every TB Wood’s coupling is delivered with detailed installation instructions. Periodic Lubrication of the coupling is required and each cover half is supplied with standard plugs which can be easily removed for re-lubrication.

Recommended Fits between Shafts and Hubs

Coupling bore tolerances for sizes up to and including 1090T can be specified to suit a clearance fit with the shaft. In these instances the hub is provided with set screws. Relative positions are given in the following table. “S” Position from Hub Faces For sizes above 1090T or where 1020 = 1.2” 1060 = 2.0” interference fits are preferred 9 1030 = 1.3” 1070 = 2.1” for smaller coupling sizes, bore 1040 = 1.5” 1080 = 2.5” tolerances will be consistent with 1050 = 1.7” 1090 = 2.8” AGMA standards.

Series 1000T10 And Series 1000T20

Dr. James Bibby originally invented the Resilient Coupling in 1917 and the 1000 Series is the latest level of this well accepted product. This Bibby Turboflex product has become universally accepted where reliable protection against shaft misalignment and vibration is desirable.

Since those early days refinements in design and material specifications have kept pace with advancing technology, achieving significant improvements in power/weight ratios.

TB Woods is proud to offer this proven product.

1000T10 1000T20 • Horizontally Split Cover • Vertically Split Cover • General Purpose • General purpose • Easy access to grid minimizes • Ideal for higher running downtime speeds • Ideal for limited space applications • Stop lug in cover prevents spinning during reversing service

High Performance The TB Wood’s Taper Grid Coupling continues that tradition. The tapered grid is made from high tensile alloy steel which is carefully formed to the grid shape before hardening and tempering under controlled conditions. The grid surface is then shot-peened. This process leaves the grid spring with a residually stressed surface layer which is in compression and which impedes the propagation of cracks. Since nearly all fatigue and stress corrosion failures originate at the surface of a part, the layer of compressive stress induced by shot-peening produces a dramatic increase in the working life and fatigue strength of the grid. This technological improvement in manufacturing process coupled with precise monitoring of raw material specification and control of trapezoidal shape, permits TB Wood’s to offer state of the art grid springs of high performance and reliability.

Scientific Design The hub is precision manufactured from high quality materials, with the hub tooth profile scientifically designed to permit progressive loading under torsional shock conditions. The combination of tapered grid and precision manufactured hub provides easy assembly. The excellent shock absorption characteristics, and the ability to accommodate misalignment protects the connected equipment.

Long Life While the coupling is designed for long life under tough conditions, maintenance and taper grid replacement can be performed quickly and easily without the need to move and realign connected equipment. Two cover design options are available in the TB Wood’s range of couplings. Both designs have been carefully engineered to provide a shaft coupling which is highly reliable and easy to install.

Reciprocating Engines For drives where the operation is near or actually Table 1A passes through a major torsional natural frequency, a mass elastic analysis of the system is advised. Number of Cylinders Service Factor When the Service Factor in Table 1 is greater than 6 and over 0.5 + S.F. Table 1 2.0, consult your supplier or TB Wood’s. 4 or less 1.0 + S.F. Table 1 Less than 4 Refer to TB Wood’s

Rating – To determine the torque rating, calculate using the procedures given on page F4-6. Information may also be found on the nameplate of the motor, etc.

Service Factor – When selecting a coupling it is important to consider the characteristics of the drive and driven equipment. A figure known as the Service Factor has been calculated based on an average of a wide range of applications. This can be used as a guide in the selection process and is displayed in Table 1 on page F4-8.

Size – In making the decision from the following product groups which is most suited to the application, select a size equal to or higher than the rating calculated. Particular attention should be made to bore sizes, and guidance for this is in the Table related to Max Bore Sizes.

Speed – Ensure that the speed is compatible.

Should full information not be supplied to TB Wood’s at the time of ordering, it will be the responsibility of the customer to ensure that the coupling has been correctly selected.

As our policy is one of continual improvement, this specification is not to be regarded as binding in any way, and is subject to alteration without notice. Certified drawings are available on request.

Coupling Application Types Table

Coupling Type Typical Applications Series

Spacer couplings are used to connect fully supported shafts with wider separations than can be reached with a close couple design. Spacer couplings allow room for installation AP, GP, TFI, Spacer Couplings GCF, GCH, Double Flex and maintenance without moving the connected equipment. Shaft separations are FSH, HSH generally in the range of 3 to 12 inches. These couplings accommodate angular, parallel and axial misalignment.

Floating shaft couplings are spacer style couplings which are designed to connect widely separated shafts. The coupling spacers are fabricated. Both steel and TrueTube composite tubing options are available.

Semi-floating shaft couplings are a special Floating Shaft single flex version of the floating shaft A5, A5C, Coupling coupling. These may be used alone for some G5, B5C RADIAL applications or in combination with floating LOAD shaft couplings and pillow block bearings to span long distances.

Composite floating shaft couplings should be SPROCKET, considered as an alternative to multiple span PULLEY, applications with center bearings. ETC.

RADIAL LOAD

Close couple designs accommodate angular, parallel and axial misalignment types where Close Couple AA, AX, AY Double Flex two fully supported shafts are located very close together. Close shaft separations are generally in the range of 1/8 to 2 inches.

Single flexing couplings compensate for RADIAL angular and axial misalignment only. Single LOAD couplings should only be used in a three bearing system with a self-aligning bearing as shown in the illustration. Single couplings Single Flex AR, GR may also be used in pairs to support a clutch, SPROCKET, PULLEY, transducer or other system component. These ETC. arrangements are double flexing and must be used with two fully supported shafts as described below. RADIAL LOAD

1) Select correct Service Factor (S.F.) from the chart below.

2) Calculate HP/100 RPM or Design Torque (lb-in). Calculate kW/100 RPM or Design Torque (Nm) HP/100 RPM = HP x S.F. x 100 kW/100RPM = kW x S.F.x 100 coupling RPM coupling RPM OR

Design Torque (lb-in) = 63025 x HP x S.F. Design Torque (Nm) = 9550 x kW x S.F. coupling RPM coupling RPM OR

Design Torque = Torque (lb-in) x S.F. Design Torque = Torque (Nm) x S.F. 3) Compare this to the HP/100 RPM (kW/100 RPM) column or the Rated Torque column. 4) Check other limiting factors such as max bores, minimum DBSE, max speed and overall dimensions.

Unit Conversions: HP x .746 = kW or kW x 1.34 = HP Nm x 8.851 = lb-in or lb-in x .113 = Nm

SERVICE FACTOR TABLE These service factors assume a smooth motor or turbine type driver. The adders listed for other driver types must be added to the service factor shown for the driven equipment.

HOW FLEXIBLE DISC COUPLINGS ACCOMMODATE MISALIGNMENT C Double flexing metal disc couplings may be used to B A accommodate angular, parallel and axial misalignment. Single C flexing couplings may only be used to accommodate angular B A PARALLEL OFFSET and axial misalignment. A metal disc type coupling uses a PARALLEL double hinge effect through two flexible discs and the spacer OFFSET to compensate for parallel offset misalignment between shafts. B A Parallel misalignment imposes the same angular deflection (A) B on each flex disc. Angular misalignment of either connected A shaft, (B), creates additional angular deflections which are added to the angular offset due to parallel misalignment. The total misalignment angle, (C), at the flex disc is equal to the angular offset due to parallel misalignment (A) plus the angular offset due to angular misalignment (B). The maximum misalignment A angle (C) should never exceed the rated misalignment capacity A of the coupling type being used. Machinery equipment changes in actual operation and over the life of the equipment. We recommend that the machinery misalignment be set as close to zero as possible when a coupling is installed. We recommend keeping the measured misalignment below 25% of the rated misalignment capacity of the coupling type used when the machinery is installed and aligned. The remaining coupling misalignment capacity will then be available to accommodate additional misalignment caused by foundation shifts, vibrations, thermal growth or other causes.

• All Torsi-Lock devices must be sized to transmit the actual application Peak Torque. The data table shows a comparison of the Torsi-Lock torque transmissibility to the coupling Peak Torque Rating as a reference. The table below does not show all possible Torsi-Lock sizes and ranges. For any Torsi-Lock requirement beyond those detailed here, please consult TB Woods Engineering (see the catalog back cover for contact information). • To determine the actual transmissible torque, as well as the actual combined hub plus Torsi-Lock device weight, from the data table, linearly interpolate between the range of values given for min and max shaft diameter. See the example interpolation calculation to the right. • The data table is applicable to keyless shaft applications only. For keyed shaft applications, either: - Use a half key in the shaft and deduct the transmissible torque value of the Torsi-Lock by 10% - Use a full height key and the overkey dimension as the Shaft Size (dw) to determine the correct Torsi-Lock size.

P-1686-TBW 7/21..... TB Wood’s 888-829-6637 F5-23 Close Coupled Couplings

PRODUCT DESCRIPTION • Used for close shaft spacing where traditional spacer couplings cannot be used • Designed for moderate speed applications • Construction includes: - Two fully machined steel hubs - One flat bar or machined block style spacer - Standard hardware and stainless steel disc packs • Form-Flex® designs use non-unitized disc packs Spacers are configured for minimal shaft separation. Shorter shaft separation is possible by allowing the shafts to extend through the disc packs into the center of the coupling. The shaft diameter must be less than the flex pack I.D. listed in the dimensional table.

TYPICAL APPLICATIONS • Machine Tools • Ball Screws • Pumps • Printing Machines

SPECIAL APPLICATIONS • Elastomeric Coupling Replacement • Cranes • Gear Coupling Replacement
